There is provided a vehicle-side charging apparatus disposed in a vehicle (2). The charging apparatus includes a power receiving coil (21) which receives power from a power transmitting coil (11) disposed in a power feeding apparatus (1) in a non-contacting manner through at least magnetic coupling, a battery (25) which is charged by reception power of the power receiving coil (21), and a vehicle-side controller (20) which controls battery charge of the battery and outputs a command of a power feeding amount to the power feeding apparatus. The power feeding amount is an amount of power feeding from the power transmitting coil to the power receiving coil. The vehicle-side controller (20) determines whether or not the vehicle (2) is to be started. The vehicle-side controller (20) outputs a command for decreasing the power feeding amount to the power feeding apparatus (1) when the vehicle-side controller (20) determines that the vehicle (2) is to be started during the power feeding from the power transmitting coil (11) to the power receiving coil (21).
Legal claims defining the scope of protection, as filed with the USPTO.
1. A charging apparatus disposed in a vehicle, the charging apparatus comprising: a power receiving coil configured to receive power from a power transmitting coil disposed in a power feeding apparatus in a non-contacting manner through at least magnetic coupling in a state in which the power receiving coil is in a position above the power transmitting coil maintaining a distance from the power receiving coil to the power transmitting coil disposed on a parking space; a battery charged by reception power of the power receiving coil; a power switch switching among a ready state in which the vehicle can travel, an on state in which the vehicle cannot travel and electric components of the vehicle can be used, and an off state in which the vehicle cannot travel and the electric components cannot be used; and a vehicle-side controller configured to control charge of the battery and outputting a command of a power feeding amount to the power feeding apparatus, the power feeding amount being an amount of power feeding from the power transmitting coil to the power receiving coil; wherein the vehicle-side controller: detects a state of the power switch during power feeding from the power transmitting coil to a power receiving coil, determines whether or not the power switch switches from the off state to the on state or whether or not the power switch switches from the off state to the ready state during power feeding from the power transmitting coil to the power receiving coil; and outputs a command for decreasing the power feeding amount to the power feeding apparatus when the power switch switches from the off state to the on state or when the power switch switches from the off state to the ready state during power feeding from the power transmitting coil to the power receiving coil.
